What a great question, because it's so difficult to provide a context in which to answer it. It's one of those questions that leads to more questions.
I guess the easy answer is, there is an infinite number of colors. It's just that humans can't see them all. The human eye has its limitations. We see only the "visible" spectrum, which is somewhat anthropocentric because when we say "visible spectrum" we mean visible to humans! Honeybees and mosquitoes see parts of the electromagnetic spectrum that we cannot.
There is literature out there that posits that ideally the human eye can detect over 16 million hues, which is why 24-bit video boards in computers were called "true-color" boards (because two raised to the power of 24 is about 16.8 million). Now 30-bit boards exist, although that increased performance is of dubious value.
